What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Jankovic Rating Scale (JRS) Change From Baseline in the JRS Severity Subscore at Week 6 After Injection (Assessed by a Blinded Independent Rater)

    The Jankovic Rating Scale (JRS) is used for classification of the patient's individual symptoms of blepharospasm and for determination of the therapeutic efficacy of study medication. The JRS sumscore is the sum of the two components of the scale:

    • JRS-Severity score which ranges from 0 (=absence of severity) to 4 (=maximum severity)
    • JRS-Frequency score which ranges from 0 (=no frequency) to 4 (=maximum frequency) The change from baseline was calculated as the score at the corresponding visit minus the baseline score.

    Measured: Baseline, week 6

Secondary outcomes (3)
  1. Jankovic Rating Scale (JRS) Change From Baseline in the JRS Severity Subscore at Week 6 After Injection (Assessed by Subject Diary)

    The Jankovic Rating Scale (JRS) is used for classification of the patient's individual symptoms of blepharospasm and for determination of the therapeutic efficacy of study medication. The JRS sumscore is the sum of the two components of the scale:

    • JRS-Severity score which ranges from 0 (=absence of severity) to 4 (=maximum severity)
    • JRS-Frequency score which ranges from 0 (=no frequency) to 4 (=maximum frequency) The change from baseline was calculated as the score at the corresponding visit minus the baseline score.

    Measured: Baseline, week 6

  2. Blepharospasm Disability Index (BSDI) Change From Baseline in the BSDI at Week 6 After Injection

    The Blepharospasm Disability Index is a scale for the assessment of impairment of specific activities of daily living caused by blepharospasm. The BSDI consists of six items (driving a vehicle; reading; watching TV; shopping; getting about on foot (walking); doing everyday activities), each ranges from 0 (=no impairment) to 4 (=no longer possible due to illness). The change from baseline was calculated as the score at the corresponding visit minus the baseline score.

    Measured: Baseline, week 6

  3. Patient Evaluation of Global Response (PEGR) at Final Visit

    The PEGR is a descriptive subjective 9-point response scale ranging from "complete abolishment of signs and symptoms" (value=+4) down to "very marked worsening" (value=-4).

    Measured: Final visit (up to week 20 after injection of the Main Period)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing incobotulinumtoxinA (Xeomin) in people with Blepharospasm, run by Merz Pharmaceuticals GmbH at 2 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Mar 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States, Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 16 Nov 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Jankovic Rating Scale (JRS) Change From Baseline in the JRS Severity Subscore at Week 6 After Injection (Assessed by a Blinded Independent Rater) (time frame: Baseline, week 6). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00406367, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Mar 2013.
